How Valuable is the Reliability of Residential Electricity Supply in Low-Income Countries? Evidence from Nepal
通过条件价值评估法,研究尼泊尔家庭在停电危机结束后对改善供电质量的支付意愿,发现家庭平均每月愿支付123尼泊尔卢比(约1.11美元)以避免停电,相当于电费增加65%。
We use contingent valuation to estimate the willingness to pay (WTP) for improved electricity service in Nepal following the end of the country’s load-shedding crisis of 2007-2016. Using a nationally representative survey of grid-connected Nepali households, we calculate the WTP per outage-day avoided and the value of lost load (VoLL) for residential customers and analyze their key drivers, including income, education, and investments in own generation or electricity storage equipment. Households are willing to pay, on average, 123 NR ($1.11) per month for improved quality of power supply. In other words, they would be prepared to see a 65% increase in their monthly bill to avoid outages. Our preferred estimates of the VoLL range from 5 to 15 NR/kWh (04.7-014/kWh). These estimates are below the marginal cost of avoided load shedding, and are virtually the same as valuations at the beginning of the load-shedding crisis.
